This invention relates to gate locks and more particularly to locks forpipe gates or the like.

An object of the invention is to provide a lock of lthe above type whichmay be easily assembled,

which is rigid and dependable in construction, and which may be lockedin either latched or unlatched position.

Another object is to provide a gate lock of the4 above type which isconstructed Aandarranged so that a pair of swinging gates may be lockedby the use of a single padlock.

Various other objects and advantages will be apparent as the nature ofthe invention is more fully disclosed.

; The invention will be better understood by referring to the followingdescription, taken in connection with the accompanying drawings, inwhich a sp'ecic embodiment thereof has been set forth for purposes ofillustration. In the drawings:

Fig. 1 is a broken side elevation of a gate embodying the presentinvention;

Fig. 2 is a section taken along the line 2-2 of Fig. 1 showing the twogates locked by a single padlock;

Fig. 3 is a vertical section of a portion of the gates shown in Fig. 1showing one of the gates latched and the other unlatched;

Fig. 4 is a transverse section taken on the line 4-4 of Fig. 3; and

Fig. 5 is a longitudinal section taken on the line 5-5 of Fig. 3.

Referring to the drawings more in detail, the invention is shown asapplied to a pair of gates i0 (Fig. 1), each of which comprises verticalmembers Il and I2, and horizontal members I3 and i4, joined together bysuitable angle or coupling members l 5 to form a frame. Internalvertical members I1 and horizontal members I8 are connected to the frameby suitable coupling members 20 and,

in the embodiment shown, are joined at the center of the gate by acoupling member 2l. Diagonal braces 22 are secured to the variouscoupling members by means of gussets 24. The entire assembly comprises apipe gate which is constructed entirely of standard pipes and couplingmembers. This gate may be secured to a post 25 forming a portion of afence, not shown, by suitable hinges 25 of standard construction. A toprail 21 is shown as extending between the two posts 25, forming theopposite sides of the gate opening.

Suitable means is provided for latching the two swinging gates i0 inclosed position when desired. In the embodiment shown, this meanscomprises a pair of rods 35 which rare held inthe upright member ii ofeach gate andare slidably secured by bushings 3l. Onerod 3U-,is adaptedto be extended into a recessed member 32,*which may, for example,comprise an iron casting secured kin the ground by pipe 33 or byothersuit-y able means.` The upper rod 30 is adapted to bear againsta'stop flange 35 which lis securedto they top rail 2l so as to latch thegate in closed position. A suitable ear 35 may be secured to the Iii4toprf the eatein a position t0 engage-theel@ of lthe top rail 2l so as`to provide -a sto-p toy prevent thegate from swinging past its centerposition. .f .f f n `When the rods 3i! are both fully extended, the l@gateis secured in closed position both at the top and bottom.' When therods Sware retracted, however, thegate is free'to swing about'the',hmgs, 26. Suitable mechanism is provided for actuating the rods 30 andfor locking the same in either extended or retracted position, as willbe described. Referring to Figs. 3 to 5, the rods'` 30 are shown asprovided with heads 40 which are quadrant-shaped in cross section andare pro-'- g5 l vided with surfaces il which are adapted to permit thetwo heads d@ to slide relative to each other as the rods 3Q areretracted or extended. The heads 40 are also provided with at topsurfaces 42 having transverse grooves 43 which are 30 adapted to beengaged by pins i4 secured to a rotatable collar 45. The grooves 43extend transversely of the respective heads 40 and register withrecesses i6 in said heads, which provide sufficient clearance to permitthe collar 45 to be 35 turned through in shifting the rods 30 fromextended to retracted positions.

The collar 45 is attached to a shaft 41 (Fig. 3), whichis mounted in abushing 48 and is secured to a handle 49. The arrangement is such that,40 with the handle 59 extending downwardly, for example, the collar 45is in the position shown in Fig. 5 with the rods 30 fully extended. Whenthe collar i5 is turned through 180 so that the handle 49 extendsupwardly, for example, the pins 45 Ml, riding in the grooves 43, causethe heads 40 to slide past each other for retracting the respective rods3U. y

For locking the handle 49 in either latching or unlatching position, thehandle may be provided 50 with an aperture 50 which is so positionedthatv the apertures 50 of the handles 49 of the two' swinging gates arebrought into registration when both gates are closed and latched and maybe secured by a single padlock 52, as shown in Fig. 1. 55

In certain instances, however, it may be desirable to lock one of thegates in latched position and the other in unlatched position. For thispurpose the bushing 48 may be provided with a laterally extending ear 53having an aperture 54 therein and the handle 49 may be provided withoppositely extending ears 55 and 56 having apertures 51 and 58 therein.When the handle 49 is in its lower position, for example, the aperture51 is brought into registration with the aperture 54 and the handle maybe secured by a padlock 59 extending through said apertures, as shown inFig. 4. When the handle 49 is in its opposite position, the aperture 58may be brought into registration with the aperture 54 and the handle maybe secured in this position by a padlock 6l) extending through saidaligned apertures. It is evident, therefore, that the two gates may beboth locked in latched position by a single padlock, as s shown in Fig.1, or they may be independently locked in either latched orunlatchedsposition by separate padlocks, as shown in Fig. 4.

For securing the latch mechanism in the vertical member Il, the bushing48 may be provided with a split collar 65, which registers with asimilar split collar B6 and may be secured by bolts 61. The entiredevice may be dismantled by removing the bolts 61 to permit the collars65 and 66 to be separated. The bushing 48 may then be withdrawn througha suitable aperture 68 (Fig. 4) in the member Il. After the bushing 48is Withdrawn, the rods 3 are free to be removed longitudinally. For thispurpose the bushings 3| may be withdrawn from the vertical members Il torelease the rods 30. In certain instances it may be desired to removeboth rods y30 from the top end of the member ll as, forexample, when thegate is permanently held in position and suiicient clearance is notprovided for removing the lower rod 30 from the bottom end of saidmember. This may be readily accomplished by removing the top bushing 3land withdrawing both rods from the top.

It is to be noted that in the above construction. the gates may besecurely and rigidly locked in either latched or unlatched positions.The construction is such that the parts will be readily assembled and,when once assembled, are substantially tamper-proof.

It is to be understood that various changes and modications may be madein the details of construction, as will be readily apparent to a personskilled in the art. A specic embodiment has been shown for purposes ofillustration only. The invention is only to be limited in accordancewith thefollowing claim.

I claim:

A latch for a swinging gate having a vertical tubular member, said latchcomprising a pair of rods disposed in said tubular member and slidablelongitudinally thereof, said rods being adapted, when extended, tosecure both the top and bottom of said gate in closed position and, whenretracted, to release said gate for swinging movement, a rotatablemember engaging said rods to extend or retract the same, a handleassociated with said rotatable member having oppositely extending ears,an ear secured to said tubular member registering with one of saidoppositely extending ears when said handle is in latching position andWith'the other of said last ears ywhenr said handle is in releasingposition, and means locking said registering ears together to preventunauthorized movement of said handle.
